Abstract

An ex-centric core photonic crystal fiber sensor with gold nanowires based on surface plasmon resonance is designed and analyzed by the finite element method (FEM). The influence of the structural parameters of the sensor on the spectral sensitivity and resonance wavelength is studied for analyte refractive indexes (na) between 1.33 and 1.4. The guided mode in the ex-centric core passes the three states of intersection, anti-intersection, non-intersection successively. The average spectral sensitivity and maximum spectral sensitivity are 7428 nm/RIU and 14,200 nm/RIU, respectively, and the refractive index resolution is 7.04 × 10−6RIU. A quality factor of 140 is achieved indicating great potential for application to biochemistry and other fields.
